Condensation detector WK02+ RS485 BACnet

humiditypotentiometermonitoring

Condensation sensor with an LED signal and a relay output to prevent condensation on chilled surfaces. For control and monitoring applications or connection to cooling valves to stop the flow of chilled water flow upon condensation. The 'ext.' model uses a 2m remote sensor for a more flexible installation. • Application/type : Condensation sensor • Purpose : Measure values • Measured values : temperature, relative humidity, absolute humidity, enthalpy, dew point, condensation • Interface : RS485 BACnet, Switch contact • Configuration : USEapp, BUS, DIP switches • Output switch contact : changeover contact, floating, max. 250 V ~, 1 A resisitve load • Network technology : RS485 BACnet (MS/TP) • Operating range temperature (°C) :0..+50 • Operating ranges temperature (°C) : 0..+50 • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : ±0,5 K (typ. at 21 °C) • Measuring range humidity : 0..100% rH non-condensing, 0..85 KJ/kg enthalpy, 0..50 | 0..80 g/m³ absolute humidity, 0..+50 | -20..+80 °C dew point, optionally configurable • Accuracy humidity : ±2% between 10..90% rH (typ. at 21 °C), potentiometer to adjust the sensitivity • Power supply : 15..24 V = (±10%) SELV, 24 V ~ (±10%) SELV • Power consumption : typ. 0,8 W (24 V =), 1,6 VA (24 V ~) • Enclosure : USE-L, impact- and shock-resistant enclosure with quick-release cover, PC • Colour : pure white, transparent cover • Protection (IP) : IP65, according to EN 60529 • Connection : removable cable entry M25 with fourfold cable entry for wire with max.
